UNDER CONSTRUCTION. EXPECT ERRORS AND OMISSIONS. FOLLOW AT YOUR OWN RISK!

The Hypertorus Fusion Reactor (HFR) is a complex long-round project, added to Atmospherics in Fusion's seventh major revision.

Words of Warning

Maintaining the HFR is hard. Maintaining the HFR is really hard. Maintaining the HFR makes managing the Supermatter Engine look like a breeze. Expect to spend half an hour just on building supporting infrastructure, then up to 15-20 minutes on running it, depending on what your goals are.

Getting the HFR operational requires knowledge of how to create uncommon gases. This typically means setting up the Incinerator to produce Hydrogen and Tritium.

Going all the way to Metal Hydrogen requires knowledge of the rarer atmospherics interactions, as well as memorizing many effects unique to the HFR.

Key parameters

Effects within Fusion reference either Fuel Consumed (F) or the Scaled rate of Production (P).

The effects we want to maximize reference P, so we try to maximize P, then set F so no excess fuel is wasted.

F = fuel injection rate / 1000 * 5 * power_level

P is clamped between 0 and F, based on heat output. Heat output tends to be either non positive or the maximum, limited by the Heating Constrictor. Once we've found a stable Heating Constrictor value for the current mix and cooling infrastructure, we can work out the ideal fuel injection rate which sets P=F, so that no excess fuel is burned.

	Fusion Level 1	Fusion Level 2	Fusion Level 3	Fusion Level 4	Fusion Level 5	Fusion Level 6
Temperature scale:	heat / 100	heat / 1000	heat / 50000		heat / 1000000	heat / 10000000
Max P:	5	5	1	10	5	30
FIR for F=P given max P:	1000	500	67	500	200	1000
Min P:	.5	.5	.1	1	.5	.5
FIR for F=P given min P:	100	50	1.34 (min 5, so always burned)	10	20	17

The Fusion mix

Optimal power is the fusion mix consists of 50% tritium and 50% hydrogen. Tritium is consumed at 0.85F, Hydrogen is consumed at 0.95F. 0.5F Helium gets produced. Counterintuitively, Anti-Noblium doesn't do anything in the fusion mix except take up space and be extremely slow to remove.

The Moderator mix

The fusion mix is always Tritium, Hydrogen, and padding. The output gases have departed, and no longer have any effect on the HFR. The moderator mix is where the most interesting effects happen.

Effects tend to reference F or P. So a gas X that gets consumes at 1.1 times the current rate of production, to produce a gas Y directly in the output port at 0.5 times the current rate of production, gets written as "Consumed x1.1P. Adds Y to Output."

Gas	Description	Fusion Level 1	Fusion Level 2	Fusion Level 3	Fusion Level 4	Fusion Level 5	Fusion Level 6
Inherent	Regardless of the contents of the moderator mix, Fusion Levels have effects of their own.	Adds CO2 x0.95P to Moderator. Adds H2O x0.75P to Moderator.	Adds CO2 x1.65P to Moderator. Adds H2O x1P to Moderator.	Adds O2 x0.5P to Moderator. Adds N2 x0.45P to Moderator.	Adds CO2 x1.65P to Moderator. Adds H2O x1.25P to Moderator.	Adds NO2 x1.65P to Moderator. Adds H2O x1P to Moderator.	Adds Anti-Noblium x0.0095F to Fusion.
Plasma	The first production moderator gas. Your bread and butter. Plasma adds a decent heat modifier to help the early fusion process, and has a high heat capacity that helps to slow change to moderator heat (and indirectly, fusion heat) in any direction, giving you much more time to react to anything that happens. Every gas with an interesting Moderator effect can eventually be produced from Plasma.	With at least 100 moles: Consumed x0.85P. Adds N2O x0.5P to Moderator.	With at least 50 moles: Consumed x1.75P. Adds BZ x1.8P to Output. Adds N2O x1.15P to Moderator.	With at least 10 moles: Consumed x0.45P. Adds BZ x1.1P to Moderator. Adds Freon x0.15P to Output. Adds Stimulus x1.05P to Output.		With at least 15 moles: Consumed x1.45P. Adds BZ x1.35P to Output. Adds Freon x0.25P to Output.	With at least 30 moles: Consumed x1.45P. Adds BZ x1.15P to Moderator.
BZ	The second production moderator gas after Plasma. Your stepping stone to Proto-Nitrate. Produces the Healium necessary to run dangerous Fusion Levels for extended periods of time, for those wanting to risk it. While Fusion Level 1 will burn through BZ rapidly with little gain, Fusion Levels 3 and above treat BZ as a catalyst, only consuming BZ at the base rate common to all gases present in the moderator mix. Massively increases radiation output. Your ability to handle Hydrogen without radiation turning it into Tritium will be very limited after this. Causes hallucinations to anyone not wearing mesons at Fusion Levels 3 and above. At Fusion Level 6, Mesons will no longer protect you from hallucinations.	With at least 150 moles: Consumed x0.95P. Adds Healium x0.75P to Output. Adds Halon x0.55P to Output. Adds Proto-Nitrate x0.25P to Output.	No effect	With at least 100 moles: Adds Proto-Nitrate x1.5P to Output. Adds Healium x1.5P to Output.		With at least 100 moles: Adds Healium x1P to Output. Adds Proto-Nitrate x1.25P to Moderator. Adds Freon x1.15P to Moderator.	If present: Adds Anti-Noblium x0.0045F to Fusion.
Proto-Nitrate	The final production Moderator gas. Produces the rarest gases. Massively increases radiation and heat, without increasing the rate of production. This means that when an active level of Proto-Nitrate is present, you will need to provide more cooling for the same level of production. Since you cannot remove moderator gases at Fusion Level 6, Proto-Nitrate's direct Output production is the only way to extract Fusion Level 6 heat. Being able to transfer Fusion Level 6 heat is necessary for Metal Hydrogen production.	No effect	With at least 20 moles: Consumed x1.35P. Increases Radiation by 55%. Increases Heat output by 2.5%, without increasing the rate of production. Adds Stimulum x1.05P to Output. Adds Plasma x1.65P to Moderator.	With at least 15 moles: Consumed x1.55P. Increases Radiation by 95%. Increases Heat output by 25%, without increasing the rate of production. Adds Stimulum x1.25P to Output. Adds Halon x1.15P to Output.		With at least 50 moles: Consumed x1.35P. Increases Radiation by 95%. Increases Heat output by 25%, without increasing the rate of production. Adds Stimulum x1.95P to Output. Adds Pluoxium x1P to Output.	If present: Consumed x3.35P. Increases Radiation by 100%. Increases Heat output by 125%, without increasing the rate of production. Adds Stimulum x2.15P to Output. Adds Zauker x5.35P to Output.
N2O	The first gas not on the main production pathway which (technically) has a special moderator effect, and the only one that is not descended from Plasma. Increases energy, but also massively decreases the heat modifier. Not very useful.	No effect	With at least 50 moles: Consumed x1.5P. Decreases Radiation by 45%. Increases Heat output by 5.5%, without increasing the rate of production. Adds Halon x1.35P to Moderator.	No effect
Freon	A safety moderator gas which quickly reduces fusion energy, and reduces the amount of cooling necessary. At high Fusion levels, decreases heat and radiation output, without (directly) decreasing the rate of production. Comes with very strong negative energy, power, heat, and radiation modifiers, so if you're planning to use this to reduce the amount of cooling required, you'll need to factor in the need for a larger moderator mix to maintain positive energy. At Fusion Level 5, has a very high threshold to activate, but has a very strong effect. Note that this almost completely removes radiation output when active, so any local Radiation Collectors will quickly drop output as well. The HFR losing power is always a catastrophic outcome unless completely inactive. This means being switched off with the first button in its interface, not just resting at Fusion Level 0! Might be useful as an emergency moderator addition when you're losing control of a reactor. Probably more useful when combined with BZ to make more Healium.	No effect		With at least 50 moles: Decreases Radiation by 20%. Decreases Heat output by 10%, without decreasing the rate of production.		With at least 500 moles: Decreases Radiation by 80%. Decreases Heat output by 50%, without decreasing the rate of production.	No effect
Healium	Directly restores integrity of a heavily damaged HFR that is operating at dangerous Fusion Levels. This is the magical red gas that will allow the daring to run the HFR at dangerous power levels for an extended period of time. However, the mechanics and their implications are quite complicated. See discussion below.	No effect				With at least 100 moles, when the HFR has taken over 400 damage (below ~56% integrity): Consumed x20P. Restores 0.11% integrity per hundred moles.

Goals

Important gases for fusion:

• Hydrogen
• Tritium
• Proto-Nitrate
• Healium

Gases to filter and process internally:

• H2O (for Hydrogen)
• Freon (for Healium; can be used in moderator if you want)

Gases to at least collect to make sure other things don't clog up:

• Pluoxium (useful directly, can also be sold for a decent price)
• Helium (can be sold for a decent price)

Gases to optionally collect to use or sell:

• Stimulum
• Nitryl (may be worth collecting to avoid decomposition)

Gases optionally collect to sell:

• Halon (if you care about fire, you're going to be using the backpack anyway)
• Antinoblium (doesn't do anything outside of fusion, but makes cashmoney at cargo)
• Zauker (currently doesn't explode with PN, so oddly safe. Bug? Intentional removal? Makes lots of cashmoney at cargo)

Setups

NB: Hydrogen won't stay as Hydrogen around radiation even when stored in a canister, now. Fuel always needs to be mixed and piped in advance now, update your designs accordingly.

The "I have four minutes before the already unrecallable shuttle arrives"

Output gases are generally favorable with desirable effects in the moderator, and can be filtered out of the moderator mix if not, provided the Fusion Level is less than 6. So the simplest HFR setup just hardpipes output gases back into the moderator port, tries to stay within safe parameters at Fusion Level 3, and sprints for the shuttle when you screw up and hit Fusion Level 6. This is extremely simple to set up, and lets one get a feel for HFR operation without risking much.

The Cargonian

Tier 3 canisters functionally tolerate any degree of pressure and temperature, even beyond what Fusion Level 6 can throw at you. So the next simplest setup involves moving sets of tier 3 canisters around, repeatedly whacking them with an analyzer or your PDA, and throwing down ad-hoc filters to extract what is useful and discard what is not.

Safety

Power

Losing power is extremely bad. The settings are forcibly set to values that are not helpful for a meltdown:

magnetic constrictor to 100
heating conductor to 500
current dampener to 0
fuel injection rate to 200
moderator injection rate to 500
no waste removal

Your previous settings are not restored when power is restored!

Additionally, iron content increases by 10 percentage points every second that the HFR goes without power (!).

Healing

Various damage and healing effects, with examples for a sense of scale:

If the power level is 5 or more:

Takes damage equal to ((((fusion_mix_moles) * 1e5 + fusion_temp) / 1e5) - 2500) / 200 per atmos tick
  Temperature of 1e8: Take 0.5 points of damage per 100 moles over 1500 moles per atmos tick
  Temperature of 5e7: Take 0.5 points of damage per 100 moles over 2000 moles per atmos tick -- point at which metal hydrogen's efficiency maxes out
  Temperature of 2e7: Take 0.5 points of damage per 100 moles over 2300 moles per atmos tick
  Temperature of 1e7: Take 0.5 points of damage per 100 moles over 2400 moles per atmos tick
  Temperature of 2e6: Take 0.5 points of damage per 100 moles over 2480 moles per atmos tick
  Temperature of 1e6: Take 0.5 points of damage per 100 moles over 2490 moles per atmos tick
Takes damage equal to log(10, fusion_temp) - 5
  2.7 damage per atmos tick at 5e7
  2 damage per atmos tick at 1e7
  1 damage per atmos tick at 1e6

If the amount of moles in the fusion mix is less than 1200, or the power level is 4 or less:

Heals (800 - fusion moles) / 150 each atmos tick
 Heals  .6 damage per atmos tick when total fusion moles are 700
 Heals 2   damage per atmos tick when total fusion moles are 500
 Heals 2.7 damage per atmos tick when total fusion moles are 394
 Heals 4.5 damage per atmos tick when total fusion moles are 125

If fusion is active, the fusion temperature is below 5e5, and the power level is 4 or less:

Heals log(10, temperature) - 5.5 each atmos tick
 Heals  .5 damage per atmos tick when fusion temperature is  1e5
 Heals 1.5 damage per atmos tick when fusion temperature is  1e4
 Heals 2.5 damage per atmos tick when fusion temperature is 1000
 Heals 3.5 damage per atmos tick when fusion temperature is  100
 Heals 4   damage per atmos tick when fusion temperature is   30

Takes damage equal to ((iron content rounded to nearest 100%) - 1) every atmos tick

The final sum from all of the above effects is capped to losing at most 0.5% integrity (taking 4.5 points of damage) every atmos tick.

In short: run with a starved fusion mix to avoid damage and start healing, and work on reducing temperature if you can.
